Title: Electric Iron
IPC: D06F75/14
Filed: 1967-08-22
Abstract: 1,191,897. Electric irons. PROCTOR-SILEX Inc. 22 Aug., 1967 [23 Aug., 1966], No. 38629/ 67. Heading D1A. An electric iron comprises at least three components including a sole plate component 10 and a handle component 50 two components being connected by two or more latching elements, operable solely by hand, so as to hold a third component in place. The iron, as shown, has the handle component 50 and the water reservoir 40 kept cool by being well above the sole plate component 10 and has connecting pins of low thermal conductivity. Reservoir 40 is made by blow moulding from thermoplastic material, e.g. transparent polypropylene, and incorporates a metallic feed valve 42 with a resilient sleeve 42a and a silicone rubber water inlet tube 43. Sole plate 11 is cast from metal with steam ports and has an integral steam chamber of the flash boiler type and a sheet metal cover 13. The heating element is preferably a rod cast into the sole plate 11 controlled by a thermostat set manually by means of lever 22 and having terminals 15a connected to sockets in a block 15 which also accommodates cord connector 70, e.g. moulded in two pieces from rigid synthetic resin. The thermostat which can be a separate unit is accommodated in the front leg 53 of the handle 50 which has an integral locking pin 56. Block 15 is accommodated in the hollow rear leg 52 of handle 50 and has integral pins 54 and a locking pin 55. Spray pump component 80 comprises a nozzle 85 and a cylinder 82 in which a plunger is reciprocated by a finger piece 83 to draw water through a tube 84 terminating in a filter element 84a which extends into the reservoir when the iron is assembled. The iron is assembled by placing component 80 backwardly and upwardly into front leg 53 of handle 50. The reservoir is then put in place with tube 84 inserted in inlet tube 43, protrusions 44 on the reservoir engaging rear handle leg 52. Between protrusions 44 in a recess 45 to receive terminal block 15 and a further recess 45a through which passes locking pin 55, springs 58 urging the reservoir forward so that a web 47b in one of two recesses 47a in the front of the reservoir engages a ring 56r on locking pin 56. The resilience of tube 43 effects the seal between it and tube extension 87. Plunger 42b of valve 42 is aligned with an actuator 61. Valve 43a on the reservoir closes during ironing but opens when the iron rests on its heel to allow air to escape during filling. The sole plate component is then assembled with the remainder, pins 54 passing through openings 16 in sole plate cover 13 to engage the sole plate and a pin 53a on front leg 53 engaging guide hole 28a. Pins 55, 56 are received respectively in tubular metal boss 17 and a boss 24 in thermostat housing 21 and have parts of reduced diameter extending beneath cover 13 and held by metal slide elements (18) Fig. 15 (not shown) carried on rivets sliding in slots in cover 16 and operated by levers 19.

Title: Seminconductor device having an integrated thermocouple
IPC: H01L35/00
Filed: 1972-08-22
Abstract: 1391214 Transistor oscillators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Aug 1972 [25 Aug 1971] 39103/72 Heading H3T [Also in Division H1] A silicon semi-conductor body 1 comprises a p-substrate 2 with an epitaxial n-layer 3 thereon in which identical transistors T1A, T1B are connected in flip-flop for one to be always conductive, in which case thermal energy is evolved in the collector-base junctions 23 and 24 underlying the emitter base junctions 10, 11. Transistor T1A has emitter n-zone 4, base pzone 5 and collector contact n-zone 6 while transistor T1B has emitter n-zone 7, base pzone 8 and collector contact n-zone 9. A thermocouple is formed by strip conductor p-zone 12 and aluminium conductors 13, 14 each of which contact zone 12 through windows of silicon oxide layer 17 and semi-conductor surface 15 to form first and second junctions 17, 18 which convert the thermal energy of transistors T1A, T1B into an electric signal between 13 and 14. Junction 17 is located near the emitter-base junction of T1A, and junction 18 is located near the emitter-base junction of T1B, the emitter-base junctions being arcuate about the CB junctions as centres (Figs. 1, 2). The circuit comprises (Fig. 3), the identical npn transistors T1A, T1B, npn transistors T2A, T2B, and pnp transistors T3A, T3B; the coupling resistors being diffused into the semiconductor and the elements being interconnected by aluminium conductors 26 to 33 and insulated one from the other by p-type separation diffusion 19 with a n-type layer 25 buried under the transistors.  In operation, the thermocouple signal at 13, 14 energizes bases of T1A, T1B over amplifiers T2A, T3A and T2B, T3B; T1A being initially conductive and T1B non-conductive so that the temperature signal from 17 is amplified to drive T1A non-conductive and T1B conductive. A similar process now occurs whereby an amplified temperature signal from 18 drives T1B non-conductive and T1A conductive and the cycles continue successively to develop an output signal across resistors R7A or R7B at frequency determined by the displacement between the collector-base junctions of T1A, T1B and the junctions 17, 18. To reduce intrinsic noise, strip zone 12 is short-circuited by aluminium layer 20. In a modification, pn junctions are used for temperature response instead of p or n and metal junctions (Fig. 4, not shown). The feedback amplifier circuit may be externally of the integrated circuit of T1A, T1B and the thermocouples, which may: alternatively operate as a differential thermostat eliminating temperature differences. A single bi-stable may be switched alternately conducting and non-conducting, and the heat generating elements may be, e.g. thyristors, resistors and diodes. The device may alternatively operate as a filter.

Abstract: 1,048,130. Refrigerating. PLESSEY-U.K. Ltd. Sept. 27, 1963 [Oct. 22, 1962], No. 39867/62. Heading F4H. Auxiliary power for an aircraft is provided by a turbine or other fluid-pressure motor which is driven by refrigerant vapour evolved during cooling of the load of a refrigeration system, auxiliary heating means being provided for heating the refrigerant when the vapour produced by the load is insufficient to supply the power required. As shown, air from the compressor of an aircraft engine is supplied through a duct 6 to a turbo-compressor 7, cooled in an inter-cooler 14 and expanded in a turbine 16 before being forwarded to an aircraft cabin through duct 12. The cooler 14 comprises the evaporator of a closed condensing-evaporating system, the refrigerant vapour from cooler 14 passing via lines 17 and 18 to drive a turbine 20 which drives an hydraulic power unit 22 and an A.C. generator 21. The speed of turbine 20 is maintained constant by an automatic valve 19. Exhausted refrigerant from the turbine 20 is condensed in a condenser 24 cooled by ram air from an inlet 26, and collected in a receiver 27, a pump 28 being provided for returning refrigerant to the cooler 14. If the vapour pressure of the refrigerant is insufficient to provide a desired output from turbine 20 the refrigerant is heated in a heat-exchanger 29, arranged downstream of cooler 14, by relatively warm air bled from duct 6 via valve controlled line 30. When the aircraft is stationary the refrigerant is evaporated in a third heat-exchanger 32 connected in parallel with line 17. The exchanger 32 is heated by a burner 33 located in a duct 34 which includes a fan 35, the latter also serving to draw air over the condenser 24. A line including a valve 39 is provided for by-passing the turbine 20 when the vapour pressure of the refrigerant is too. high. Hydraulic lines 40 lead from the power unit 22 to starter motors for the aircraft engines. Alternatively refrigerant vapour from the heat-exchanger 32 may be used to operate the starter motors or the unit 22 and generator 21 may be replaced or supplemented by a vapour generating or pneumatic-pressure generating plant for starting purposes.
